APC describes Smart-UPS as intelligent and efficient network power protection for servers, point-of-sale systems, routers, switches, hubs and other network devices.
The family includes multiple capacities and form factors, so model selection should begin with the supported load and electrical environment rather than assuming every Smart-UPS is interchangeable.
Key design choices include rack versus tower format, input/output voltage, watt and VA capacity, outlet configuration, runtime, external-battery capability, communications and whether the application instead calls for the Smart-UPS On-Line or Smart-UPS Ultra branch.
For a rack of IT equipment, total the measured or nameplate wattage of servers, storage and networking gear, then account for expected growth. Keep the planned continuous load below the applicable UPS output limit and verify the receptacles match the installed power cords or PDU.
Runtime is a load-dependent engineering value. External battery packs can extend runtime on compatible Smart-UPS models, but the battery pack must be approved for that specific UPS family and model.
No. Smart-UPS is a broader family. APC also has a specific Smart-UPS On-Line range using online double-conversion topology.
No. External battery packs are model-family specific. Verify the exact UPS and APC-supported battery pack combination.
